RAILWAY TIE.

Application filed November 19, 1924.

This invention relates to metal railway ties and has for an object the provision of a tie of this character which is light, strong and durable in construction, having means for reinforcing the tie beneath the rails and means for securing the rails to the tie in a simple and effective manner, the construction admitting of the manufacture of ties for use as cross ties, switch and bridge ties.

Vfith the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation of a tie con structed in accordance with the invention, the rails being secured in place and shown in cross section.

Figure 2 is an enlarged transverse sectional view on the line 22 of Figure 1.

Figure 8 is an enlarged fragmentary elevation showing a portion of the tie with the rail in section.

Figure 1- is an enlarged section on the line tlof Figure 3.

Figure is a fragmentary elevation of one end of the tie showing the outside members in position.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the tie which is constructed of metal is substantially rectangular in form and includes upper and lower walls 10 and 11. respectively and end walls 12, these walls being connected by a web 18 which extends centrally and longitudinally of the tie, so that the tie has the cross sectional shape of an I beam.

The top wall 10 is provided with spaced depressions 1- and these depressions are arranged in pairs so that a rail plate is provided between each pair of depressions, while at each side of the rail plate there are provided spaced shoulders 16 and 17.

The rails which are indicated at R rest upon the rail plates 15, the width of the lat ter being governed by the width of the base flange of the rails. Clamps 18 serve to hold Serial No. 750,862.

the rails in position and these clamps are provided at one end with a rail flange engaging portion while their opposite ends fit within the depressions let and engage the shoulders 16 and 17. The plates are thus held against relative horizontal movement and are secured to the tie by means of bolts 19, there being preferably two bolts for each clamp.

For the purpose of reinforcing the tie and bracing the latterat the points of greatest strain there are provided spaced oppositely extending transversely disposed ribs 20 and 21. The ribs 20 extend beneath the edges of the rail plates 15, while the ribs 21 are arranged intermediate the ribs 20.

A layer of fiber or other insulating material 22 is provided between the tie and the clamps 18 as shown in Figure 3 of the drawings, the upper face of the rail plate being provided with depressions 23 into which the insulated fiber pad will bite due to pressure of the trains.

In Figure 5 of the drawings the rail R is shown as braced by an inclined brace 24-, the upper end of which engages beneath the ball of the rail R while the opposite end is secured upon the clamp 18 by means of the clamp securing bolts 25. The outer edge of the brace 24- engages a shoulder 17 a which is spaced from the adjacent edge of the rail plate 15 and which extends upwardly above the clamp 18 for this purpose.

The tie is provided with a protective bituminous coating to increase its durability.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is A railway tie comprising a hollow rectangular member including top, bottom and end walls, a longitudinally disposed central web connecting the walls, spaced depressions provided in the upper face of the top wall,

said depressions being arranged in pairs and defining rail plates having shoulders at th ir opposite edges and parallel shoulders spaced outwardly from the first mentioned shoul- Wells and a plurality of depressions formed dei's, oppositely disposed ribs extending in the upper face of the rail plates as fer the from the central web beneath each end of the l purpose specified. 10 mil plates and connecting the top and hot- In testin'iony whereof I affix my signatoni Walls and'transversely disposed interture.
